php: calling protected methods without inheritance

Sometimesyou need to call a protected method without inherit from it.
This can be done by integrating the magic method __call()

Here is an example from php.net

yield_something(function($data) use (&$self)
   {
     $self->debug("Doing stuff to the data");
     // do something with $data
     $self->debug("Finished doing stuff with the data.");
   });
}

// Ah-Ha!
public function __call($method, $args = array())
{
   if(is_callable(array($this, $method)))
     return call_user_func_array(array($this, $method), $args);
}
}

$fun = new Fun();
echo $fun->having_fun();
